One of the best parts of building a custom PC is making it your own, since no two custom-builds will end up exactly the same. There are a lot of ways to make your high-end gaming PC uniquely stand out from the rest, including by picking a stylish PC case, adding RGB components and accessories, and creating a custom cooling system. Those are classic, tried-and-tested options that date back to the early days of PC building. In 2024, there’s a new option, and in many ways it’s better and more uncommon than the others. You can install something known as a sub-screen into your existing PC case, and it’s a secondary display that can display graphics, widgets, performance stats, and much more.
